In a recent article in Medium, Kris Perry, Executive Director of the First Five Years Fund, discusses the need to move past the debate of whether or not preschool works, and instead focus on innovation, experimentation, and evaluation. Perry argues that research has consistently shown the academic and economic benefits of preschool, especially for disadvantaged children. Therefore, the question is no long effectiveness, but rather, how to bring quality early childhood programs to scale for children from birth to age 5.
